#412Lighthouse Beam

A lighthouse sweeps its lamp across a fogbound night. The beam is the dot of the view direction against a rotating axis, raised to a tight power so it reads as a hard shaft, then scattered through drifting volumetric fog and dimmed with distance. A blazing lamp core blooms above a black tower silhouette, stars prick the deep-blue sky, and a fainter back-beam trails the sweep. Scroll spins the lamp faster, the pointer nudges its aim, and a press flares the whole shaft brighter.
